I took three cuttings from a plant in someone's garden some time ago and all survived - I now have three lovely little plants, flowering happily in October, which neither I nor any of my friends or neighbours can identify. The leaves are dark green, toothed, and around 6cm long; the flowers (white with dark pink and green centres) are small and roughly 1cm across. Has anyone any ideas?
I think your plant is likely to be what used to be called Parahebe catarractae (G.Forster) Oliver from New Zealand. This genus is similar to Hebe and like it I expect that current taxonomic thinking has it sunk back into a huge genus Veronica. It is rather more floriferous than the other Parahebe species which are grown and has longer leaves (>1.5cm).
Hi Dr Fred - yes, I'm sure you're right!! There are lots of photos of the Parahebe catarractae 'Avalanche' on the net and it looks identical to my mystery plant.
Thank you so much - can't tell you how pleased I am to know what it is at last!
